We are currently using Redis as our data store. I am making a new section where we need to rank and paginate users. So i am thinking to use Sorted set for keeping rank and userid. And Hash for keeping user's profile data. It was brought to my attention by a colleague that we ll need to make many requests to redis to fetch users profile data using HGET. so Round trip time is going to be an issue. I was planning to use HMGET but After doing some research i found it may cause issues when Redis is clustered because Keys are stored in different redis nodes. I am using phpredis it has client side-sharding (I am having trouble understanding what that is).
